Description
(Visible when
92.01 Encoder 1 type
Enables the encoder zero pulse for the absolute encoder
input (X42) of the FEN-11 interface module.
Note: No zero pulse exists with serial interfaces, ie. when
parameter
92.11 Absolute position source
Hiperface,
SSI
or Tamagawa.
Zero pulse disabled.
Zero pulse enabled.
(Visible when
92.01 Encoder 1 type
Defines the number of pole pairs of the resolver.
Number of resolver pole pairs.
(Visible when
92.01 Encoder 1 type
Selects whether position estimation is used with encoder 1 to
increase position data resolution or not.
Measured position used. (The resolution is 4 × pulses per
revolution for quadrature encoders, 2 × pulses per revolution
for single-track encoders.)
Estimated position used. (Uses position interpolation;
extrapolated at the time of data request.)
(Visible when
92.01 Encoder 1 type
Defines the number of bits used to indicate position within
one revolution. For example, a setting of 15 bits corresponds
to 32768 positions per revolution.
The value is used when parameter
source
is set to EnDat,
Hiperface
92.11 Absolute position source
parameter is internally set to 17.
Number of bits used in position indication within one
revolution.
(Visible when
92.01 Encoder 1 type
Selects whether calculated or estimated speed is used.
Estimation increases the speed ripple in steady state
operation, but improves the dynamics.
Last calculated speed used. (The calculation interval is 62.5
microseconds to 4 milliseconds.)
Estimated speed (estimated at the time of data request) is
used.
(Visible when
92.01 Encoder 1 type
Defines the number of bits used in revolution counting with a
multiturn encoder. For example, a setting of 12 bits would
support counting up to 4096 revolutions.
The value is used when parameter
source
is set to EnDat,
Hiperface
92.11 Absolute position source
this parameter to a non-zero value activates multiturn data
requesting.
Number of bits used in revolution count.
(Visible when
92.01 Encoder 1 type
Activates transient filtering for the encoder (changes in
direction of rotation are ignored above the selected pulse
frequency).
Change in direction of rotation allowed below 4880 Hz.
